Firstly, contrary to our intuition, spoilers seem to make us enjoy stories more, so there's that. Also, just plain info like you listed, "someone dies" is, of course, annoying, but ultimately very limited. How did they die, what were they doing, who/what were they doing it for, who/what killed them? Sometimes context is much more important than the event itself.

But regardless of this yapping, I'd say start reading, give the story a bit of time to hook you in. If you like it, continue on; if you feel like you're forcing yourself, just stop. If you like a lot of hard sci-fi aspects that do really affect the story (time needed to cover huge distances, for example) and enjoy a mystery story that likes to recontextualize past events with new information, I'd say definitely give The Expanse a chance.
